Tilemap 给Tileset绑定Material无法显示并且关闭再开绑定的Material就会丢失

Shader就是输出纯红色

Shader3D Start

    type:Shader3D,
    name:Shader_TilemapBrush_DebugRed,

    supportReflectionProbe:true,

    },
    attributeMap: {
        a_position: ["Vector4", 0],
        a_color: ["Vector4", 1],
        a_uv: ["Vector2", 2],
    },
    defines: {
        BASERENDER2D: { type: bool, default: true }
    }
    shaderPass:[

            FS:baseRenderPS

首次绑定


此时绘制是什么都绘制不上去的

控制台是不报错.

但是只要关了再开
场景是有无材质时候的样式并且材质丢失

直接打开Mat文件材质是引用到的

您好，可以上传一个demo嘛

Old King

几个问题.

首先
https://layaair.com/3.4/doc/IDE/Component/2D/2DRender/Mesh2DRender/readme.html
文档中的Shader是不能用. 应该是你们后来更改的方案但是文档中的还是旧的. 所以只要用这个就报错.
需要更改为我下面这个新的写法


Shader3D Start
{
    type:Shader3D,
    name:baseRender2D,
    enableInstancing:true,
    supportReflectionProbe:true,
    shaderType:D2_BaseRenderNode2D,
    uniformMap:{
        u_gradientDirection: {type: Vector2, default:[1,1]},    // 渐变方向
        u_gradientStartColor: {type:Vector4, default:[1,1,1,1]},       // 渐变起始颜色
        u_gradientEndColor: {type:Vector4, default:[1,1,1,1]}        // 渐变结束颜色    
    },
    attributeMap: {
        a_position: ["Vector4", 0],
        a_color: ["Vector4", 1],
        a_uv: ["Vector2", 2],
    },
    defines: {
        BASERENDER2D: { type: bool, default: true }
    },
    shaderPass:[
        {
            pipeline:Forward,
            VS:baseRenderVS,
            FS:baseRenderPS
        }
    ]
}
Shader3D End

GLSL Start
#defineGLSL baseRenderVS

    #define SHADER_NAME baseRender2D

    #include "Sprite2DVertex.glsl";

    void main() {
        
        vertexInfo info;
        getVertexInfo(info);
        gl_Position = getPosition(info.pos);

        v_texcoord = info.uv;
        v_color = info.color;

        #ifdef LIGHT_AND_SHADOW
            lightAndShadow(info);
        #endif
    }

#endGLSL

#defineGLSL baseRenderPS
    #define SHADER_NAME baseRender2D
    #if defined(GL_FRAGMENT_PRECISION_HIGH) 
    precision highp float;
    #else
    precision mediump float;
    #endif

    #include "Sprite2DFrag.glsl";

    void main()
    {
        clip();
        vec4 textureColor = texture2D(u_baseRender2DTexture, v_texcoord);

        // 计算渐变因子
        float gradientFactor = dot(v_texcoord, normalize(u_gradientDirection)) * 0.5 + 0.5;

        // 混合渐变颜色
        vec4 gradientColor = mix(u_gradientStartColor, u_gradientEndColor, gradientFactor);
        textureColor *= gradientColor;

        #ifdef LIGHT_AND_SHADOW
            lightAndShadow(textureColor);
        #endif

        textureColor = transspaceColor(textureColor);
        setglColor(textureColor);
    }

#endGLSL
GLSL End

Tilemap的Material似乎是不能用的.我让AI看了下Github上的源码. 应该是Tilemap的Tileset的Shader需要TS这边去注册. 直接挂Material是无效

import TileMapVS from "./TileMap.vs";
import TileMapFS from "./TileMap.fs";
import TileMapVertexGLSL from "./TileMapVertex.glsl"
import TileMapFragmentGLSL from "./TileMapFragment.glsl"

Shader3D.addInclude("TileMapVertex.glsl", TileMapVertexGLSL);
Shader3D.addInclude("TileMapFragment.glsl", TileMapFragmentGLSL);

let shader = Shader3D.add("TileMapLayer", false, false);
shader.shaderType = ShaderFeatureType.Effect;

let subShader = new SubShader(attributeMap, {}, {});
shader.addSubShader(subShader);
subShader.addShaderPass(TileMapVS, TileMapFS);

我试了纯红色块的Shader

Shader3D Start
{
    type:Shader3D,
    name:Mesh2DTestRed,
    enableInstancing:true,
    supportReflectionProbe:true,
    shaderType:D2_BaseRenderNode2D,

    uniformMap:{
    },

    attributeMap: {
        a_position: ["Vector4", 0],
        a_color: ["Vector4", 1],
        a_uv: ["Vector2", 2],
    },

    defines: {
        BASERENDER2D: { type: bool, default: true }
    },

    shaderPass:[
        {
            pipeline:Forward,
            VS:baseRenderVS,
            FS:baseRenderPS
        }
    ]
}
Shader3D End

GLSL Start

#defineGLSL baseRenderVS

    #define SHADER_NAME baseRenderVS

    #include "Sprite2DVertex.glsl";

    void main() {
        vertexInfo info;
        getVertexInfo(info);

        v_texcoord = info.uv;
        v_color = info.color;

        #ifdef LIGHT2D_ENABLE
            lightAndShadow(info);
        #endif

        gl_Position = getPosition(info.pos);
    }

#endGLSL


#defineGLSL baseRenderPS

    #define SHADER_NAME baseRenderPS

    #if defined(GL_FRAGMENT_PRECISION_HIGH)
        precision highp float;
    #else
        precision mediump float;
    #endif

    #include "Sprite2DFrag.glsl";

    void main()
    {
        clip();

        vec4 textureColor = vec4(1.0, 0.0, 0.0, 1.0);

        textureColor = transspaceColor(textureColor);
        setglColor(textureColor);
    }

#endGLSL

GLSL End

这个在MeshRender2D的节点是可用的. 但是Tilemap给Tileset绑定则直接报错.

我直接右键新建一个纯新的 Shader ,然后纯新的Material

这个挂在Tile上则不报错无任何反应关了再开直接丢失.
